When trying to install my cam chest cover it starts to bind up when it is about halfway on. At that point the the wheels are bound as well. Everything moves freely without the cover on. The cams slide easily into the bushings in the cover when out of the crank case.

If it actually binds up halfway on, it would sound to me like you have the wrong cam gear [later cam gear] in the rear intake position or you have the wrong gear cover for the cam set being used. It would be an endplay issue.

If memory serves me correctly, the length difference between early and later cam gears is roughly 3/32". Will the cover go on all the way if you do not have any of the cam gears in it ? You can also tell if you have the wrong cam in it if the cam lobe looks to be off center when looking down through the tappet block opening.

Pa, yes the cover goes on fine with an empty chest. I will try installing one cam at a time then the cover to see just when the binding starts. Just need to get home so I can spend some quality time with my project.

I have been out of the country just getting home for Christmas. Finally had a little time to play with this problem today and it seems Pa is correct. The #2 cam sits proud of the cam chest mounting surface by about 3/16 inch. Not sure why it took this long for me to notice that.

Thanks all and Merry Christmas.

You are not the first to learn of this type of issue. I learned the way you learned.

I once got a fortune cookie that read "To be old and wise you must first be young and stupid"We all learn from stupid things like this. Glad you found it before bolting on the cover and breaking things.I'm still waiting for the last part of the fortune to finish up.
